Premium Forged 7075-T6 Aluminum Construction

The forging process creates a dense, durable receiver that resists cracking and deformation under stress.

The precise machining of the receiver’s interior and exterior surfaces guarantees proper alignment and smooth operation once the rifle is assembled.

Stripped Design for Full Customization

As a stripped upper receiver, the RF00721 contains no installed parts. This gives builders complete control over every component of their build. You can choose the exact handguard, charging handle, forward assist, dust cover, and other parts that best suit your needs and preferences. This level of customization is ideal for competition shooters, tactical users, and hobbyists who want to create a truly personalized AR-15 rifle.
